NURSING BOTTLE.

Application filed August 18, '1923. Serial No. 658,013

To all whom it may concern Be it known that I, Lnsrnn SEJARTO, a

citizen of the Republic of Hungary, residing at Linden, in the county of Union, State of New Jersey, have invented new and useful Improvements in Nursing Bottles, of

which the following is a specification.

My invention relates to nursing bottles within whicha detachable tube is mounted, and the object of my invention is to provide in a nursing bottle, a tube so designed and arranged as to permit the withdrawal of milk from the bottle by the nursing infant, when it is placed at any angle below the horizontal without interfering with the removal of milk in the usual manner when the bottle is held in an inverted position or at any angle above the horizontal.

The tube, which may be easily removed is preferably made of glass and can therefore be effectively cleansed and sterilized and is highly sanitary. Further objects of the invention are hereinafter set forth.

My invention is fully described in detail in the following specification and drawings forming a part thereof in which latter I. have illustrated a preferred embodiment of my invention. Referring to such drawings, in which similar reference characters refer to similar parts in each of the views. I

Fig. 1 is a vertical section of a nursing bottle provided with my improvement,

Fig. 2 is a similar view on a smaller scale with the bottle inverted,

Fig. 3 is an elevation, partly in section, of a. modified form and Fig. 4: is another modification of the invention.

In the drawing 1 represents a nursing bottle of the usual type, 2 a nipple thereon, 3 a tube of glass or other suitable material having an enlarged upper portion 4 with an orifice 5 at the top thereof.

The tube 3 is open at the lower end and may be provided with several weakened sections 6 to permit the breaking off of a suflicient amount of the tube to fit bottles of varying length, it being desirable to have the lower extremity of the tube in close proximity to the bottom of the bottle.

The enlarged portion 4: is of suitable configuration to pass partially within the neck of the bottle and be suspended therefrom so that the tube is free to swing about univer+ sally within the bottle and al y fall against the lower side when the latter is inclined as in Fig. 3, thus permitting the en tire contents to be withdrawn.

This is accomplished by the suction on the nipple 2, the latter partially collapsing and engaging the top surface of the enlarged portion 4, forming a seal which causes the milk to rise in the tube, and if the bottle is partially rotated the tube will continue to engage the lower side of the bottle and effectively deliver the entire contents.

WVhen the bottle is inverted as in Fig. 2, the tube will drop through the neck and will fall into an inclined position such downward movement being limited by the engagement of the enlarged portion 4, with the walls of the nipple. This inclined position will form an irregular contact with said walls due to the staggered relation of the engaging surfaces so that when suction is applied to the nipple, the milk will pass between the portion 4 and the adjacent walls of the nipple, the tube now serving as a return passage for the air which must necessarily relieve the partial vacuum above the milk. 7

I have found the modified form of tube illustrated in Fig. 3, with a spherical terminal portion 4 to be a useful improvement in nursing bottles but prefer to use the shape shown in Figs. 1 and 2,as the flow of the milk is greater when the bottle is inverted and when in an upright position the top portion provides a greater surface for contact with the nipple to more effectively form a union therewith.

The modification in Fig. at, shows the terminal portion 4 as a solid sphere through which the bore of the tube passes thus eliminating any undesirable pockets which would 7 be unsanitary.

Changes in detail of construction which are merely matters of form ordesign are to be considered within the scope of the invention. 7

I claim:

1. A nursing bottle which comprises a body-portion, a neck, a nipple, and a headed tube freely suspended by said head from the bottle neck, thereby permitting the tube to rock freely in response to the varying movements of the bottle when in an upright position, said tube being also adapted to move axially within the bottle when the latter is inverted so that the headed portion will then fall away from contact with the bottleneck.

2. A nursing bottle which comprises a body-portion, a neck, a nipple, and a headed tub-e freely suspended by its head from the neck of the bottle, the head of the tube extending above the top of the bottle for engagement with the Walls of said nipple when suction is applied thereto, said tube and head being also free to move along the longitudinal axis of the bottle when the latter is inverted, and tilt so that milk may then be drawn around the outside of said head.

In testimony whereof, LESTER SEJARTO has signed his name to this specification this 15th day of August 1923.

LESTER SEJARTO.
